This #NationalMentoringMonth, we want to highlight those lost on 9/11 who went above and beyond for their communities. James Trentini lived in Massachusetts with his wife, Mary Trentini. The couple had four grown children. A former teacher, coach, and assistant principal, Trentini had retired as the head of the Burlington School District health education department. On 9/11, he and Mary boarded Flight 11 for California to visit and babysit three of their grandchildren. Trentini was 65 years old. Mary was 67 years old.
